Gas hydrates are crystalline clathrate compounds comprised of hydrogen-bonded water cavities,consisting of guest molecules trapped in a lattice of polyhedral water cages under elevated pressures and low temperatures[1].The structures of the gas hydrates are closely related to the types and sizes of the guest species,and three distinct structures,including cubic structure-Ⅰ(sⅠ),cubic structure-Ⅱ(sⅡ),and hexagonal structure-H(sH),are known to form[2].Being expected as a kind of future energy resource,natural gas
